“Our tax returns will bore you to death,” Sanders said in response to moderator Wolf Blitzer’s question about financial transparency. “It just was a mechanical issue. We don’t have accountants at home, my wife does most of it, and we will get that stuff out.”

The National Journal had reported earlier Monday that Sanders would be announcing the release, and the presidential candidate confirmed it during the CNN town hall on Monday evening.

Some lawmakers criticized Sanders for not being transparent about his finances during the 2016 Democratic primary, when he only released his tax returns from 2014.

The Vermont senator did not give a timeline Monday for when he would release his tax returns, but said they will be made public “soon.”

President Donald Trump has refused to release his tax returns, separating from decades of tradition. Democrats have denounced him for the lack of transparency, saying he may be hiding potential conflicts of interest.

Warren has urged all presidential candidates to release the last 10 years of their tax returns, noting she’s done so already.

Our candidates should be held to the highest standards of accountability. That’s why I proposed a plan to #EndCorruptionNow. That's why I put 10 years of my tax returns online. And that's why our movement is powered by grassroots supporters – not federal lobbyists or Super PACs.
